PerfMonger is an yet another performance monitoring tool. The monitoring targets of PerfMonger are similar to the ones of sysstat (CPU usages, IO usages, etc.), but PerfMonger can collect and report performance information very frequently (the reporting interval of sysstat is 1 second at minimum, but PerfMonger can use a much smaller interval such as 0.5 seconds or 0.01 seconds) and can display performance information in both human-readable and machine-readable formats.

Task Stalker provides visual process monitoring and management for Linux. Its features include live process accounting, a graphical view, recording of a task’s state changes, display of CPU activity, and basic system information display.

ZedLog is a robust cross-platform input logging tool (A.K.A., a key logger). It is based on a flexible data logging system which makes it easy to get the required data. It features logging of all keyboard and mouse events, a replay simulation tool, logging to a file, and hiding in the background.

BOINCmon is a graphical package to monitor BOINC activity on multiple computers over a network
or multiple instances on the same computer.
It can monitor multiple PCs without having to cross-mount filesystems.

copymon provides file copying processes with a progress bar. Neither cp nor rsync provide means to monitor the copying process, nor a progress bar. copymon is a wrapper which performs a scan of the directory to be copied and collects information about the files to be copied. After that, it spawns the actual copying program (which can be cp, rsync, or tar) and monitors its progress. copymon can be easily enhanced to support more programs and can be extended to provided different types of progress bars.

OpenVPN-Monitor is a simple program to generate HTML to display the status of an OpenVPN server, including all current connections. It uses the OpenVPN management console. It typically runs on the same host as the OpenVPN server.

MN Viewer (Mobile Network Viewer) is a lightweight framework designed for system administrators who would like to be able to monitor many aspects of their network from their mobile phone. It allows for very simple expansion using simple PHP plugins. It is designed to integrate with other monitoring tools such as Cacti.

Redshiftgui changes the color temperature of your monitor to better match that of your surrounding. This means that it sets a cooler color temperature during the daytime (due to natural lighting) and sets a warmer temperature at night (due to indoor lighting). Similar to f.lux, this is a GUI port of the redshift project.
